What are the folder names which cannot be created?

Certain folder names cannot be created in most operating systems due to reserved keyWords. Common examples include "CON," "PRN," "AUX," "NUL," "COM1" through "COM9," and "LPT1" through "LPT9," which are reserved for system devices in Windows. Additionally, names that include special characters like slashes, backslashes, colons, asterisks, question marks, and others are also prohibited. Lastly, folders cannot have names that are empty or contain only whitespace.
